Abstract

See full text

An apparatus and method for establishing a trusted path between a user interface and a trusted executable, wherein the trusted path includes a hypervisor and a driver shim. The method includes measuring an identity of the hypervisor; comparing the measurement of the identity of the hypervisor with a policy for the hypervisor; measuring an identity of the driver shim; comparing the measurement of the identity of the driver shim with a policy for the driver shim; measuring an identity of the user interface; comparing the measurement of the identity of the user interface with a policy for the user interface; and providing a human-perceptible indication of whether the identity of the hypervisor, the identity of the driver shim, and the identity of the user interface correspond with the policy for the hypervisor, the policy for the driver shim, and the policy for the user interface, respectively.
